Comprehensive Description of a Presentation on Sexually Transmitted Infections (STIs)
Introduction
Sexually Transmitted Infections (STIs), also commonly referred to as Sexually Transmitted Diseases (STDs), represent a significant global public health challenge. This presentation is designed to provide a thorough understanding of STIs, emphasizing their causes, modes of transmission, signs and symptoms, preventive measures, diagnostic techniques, and treatment options. The purpose of this presentation is not only to educate but also to promote responsible sexual behavior, reduce stigma, and encourage timely medical intervention.
The audience for this presentation may include adolescents, young adults, parents, educators, healthcare professionals, and community members. Whether delivered in schools, universities, health seminars, or public outreach campaigns, this presentation will be highly informative and accessible.
---
Section 1: What Are Sexually Transmitted Infections?
STIs are infections that are primarily spread through sexual contact, including vaginal, anal, and oral sex. Some infections can also be transmitted through non-sexual means such as blood transfusion, shared needles, or from mother to child during childbirth or breastfeeding. While some STIs are caused by bacteria, others result from viruses, parasites, or fungi.
Common bacterial STIs include chlamydia, gonorrhea, and syphilis. Viral STIs include HIV, herpes simplex virus (HSV), human papillomavirus (HPV), and hepatitis B and C. Parasitic STIs include trichomoniasis and pubic lice. The presentation begins by explaining these basic distinctions to provide a solid foundation.
---
Section 2: Global and Local Epidemiology
This section explores current data and trends. STIs affect people across the world, with the World Health Organization (WHO) estimating that more than 1 million STIs are acquired every day worldwide. Particular emphasis is placed on vulnerable groups such as adolescents, young adults, and people with multiple sexual partners.
Graphs and visual aids will display statistics related to prevalence, incidence rates, and demographic trends. Comparisons between countries and regions will help contextualize the issue globally and locally. The goal is to illustrate that STIs are not limited by geography, race, or socioeconomic status—they can affect anyone who is sexually active.
---
Section 3: Common STIs and Their Characteristics
Here, the presentation dives deeper into individual STIs. Each infection will be discussed in terms of:
Pathogen (bacterial, viral, etc.)
Mode of Transmission
Symptoms and Complications
Diagnosis
Treatment Options
Prevention Strategies

Preface and introduction to the
course
State the common occurring STIs in Malawi.
Describe current methods of safer sex that you
have heard about in Malawi.
State in broad terms the significance of STIs in
Malawi.
3
Obj………………………….
Describe the three modes transmission of
STIs
Describe the links between HIV and other
STI.
4
Preface
Malawi government adopted the Syndromic
approach management of STIs in 1992.
The MOH was assisted by JSI-STAFH project in
the implementation in 5 pilot sites.
Based on JSI-STAFH evaluation 1997, trainers
and service provider’s were revised and the
training was extended to two weeks
5
Additional focus to the approach
Focus on the human aspects (psychosocial
component).
Involvement of sexual partners in treatment.
Community aspect
Condom promotion
6
Significance of STIs in Malawi
Malawi has high rates of sexually transmitted
infections.
HIV prevalence is estimated at 14.2% at
national level.
Concern on syphilis prevalence, 3.9% (NAC
2001).
High STI incidence and high HIV prevalence
drain limited resources.
7
Significance………………………
STI is the fourth common reason for out
patient visit.
Asymptomatic nature of some STI remains a
challenge ( 80% of STIs are asymptomatic
esp. in women)
8
consequences
Blinding eye infections
Infertility
Spontaneous abortions
Ectopic pregnances
Cervical cancer
Death
Chronic abdominal pains- infertility in women
Infertility in men- gonorrhea & chlamydia
9
Consequences………………..
Increased risk of HIV infection
Irreversible damage to the brain and heart
Extensive organ and tissue destruction in
newborns.
Social disruption
10
Major modes of transmission
Unprotected sexual intercourse with an
infected partner (Main mode – >80%)
Mother to child transmission (in utero or
during birth.
Breast feeding – esp HIV .
11
Link between STIs and HIV
Measures of prevention are the same
Modes of transmission are the same
HIV affects the treatment response to STIs
STI increases risk of getting HIV (5-10 times)
HIV infection may complicate STI diagnosis
STI symptoms may be more severe in HIV +ve patients.
Treating STI effectively reduces transmission of HIV
significantly.
12
HISTORY TAKING
AND EXAMINATION
13
TWO IMPORTANT REASONS FOR OBTAINING A
THOUROUGH HISTORY.
It helps the service provider learn about the
client’s symptoms- increase in diagnostic
reliability.
It provides valuable information for
prevention, counselling and partner
notification and treatment.
14
IMPORTANCE OF THE SERVICE PROVIDER
GAINING CLIENT’S TRUST.
The client may feel uncomfortable talking
about sex.
The client may withhold information to protect
sexual partners
The client may feel intimidated by service a
provider of a different social status or speaks
of a different language.
15
WAYS A SERVICE PROVIDER CAN HELP A CLIENT FEEL
MORE AT EASE
Greet the client in a friendly manner
Make sure that your body gives the same friendly, relaxed
message as your words.
Speak whichever the language the client indicates is most
comfortable for talking about sexual issues
Ask the client’s permission to bring up personal questions.
Avoid dwelling on sensitive issues
Phrase your questions politely
Ask one question at a time
Use non medical terms
16
Cont`d
Avoid leading questions
Keep your questions free from moral
judgement
Make questions specific and clear
17
COMPONENTS OF THE ‘GATHER’ PROCESS USED IN
OBTAINING THE HISTORY AND THE TYPES OF
INFORMATION TO BE OBTAINED.
First three steps of the ‘GATHER’ process
GREET, ASK and TELL
General details
Symptoms of present illness
Specific questions for female clients
Medical history, especially previous history of STIs
and or STI treatment.
Sexual History.
18
IMPORTANCE OF PERFORMING A PHYSICAL
EXAMINATION ON A CLIENT
It enables the provider to confirm the
symptoms the client has described.
It allows the provider to confirm or rule out
various syndromes.
19
POINTS TO CONSIDER BEFORE PERFORMING A
PHYSICAL EXAMINATION
Explain to the client what is going to be
done
Ask for his/her verbal consent
Provide privacy
Wear gloves only when examining genital
area.
20
Role Play Script
Service Provider’s Role
You are a service provider working at an STI clinic. Today Mrs. Ngozo reports to
your clinic with a STI problem. However, her husband has no problem.
Your job is to obtain a complete history and perform a thorough physical
examination.
Client’s Role
You are Mrs. Ngozo, aged 30 years. You work at Tidziwane Rest House as a
housekeeper. You live with your husband in the nearby village. Your husband is 40
years old, a business man who sells fish in the urban areas and travels quite often.
You consider your relationship with your husband to be good. However, you have
not discussed the present problem with him.
Today you have come to the STI clinic complaining of pain when passing urine,
excessive vaginal discharge, lower abdominal pain and pain during intercourse.
You are concerned that your husband may have been unfaithful while travelling for
his work. You decide to talk to the Service Provider about this concern.
21
SYNDROMIC MANAGEMENT OF STIs
Based on the identification of consistent and
similar groups of symptoms and signs
(syndromes), and the provision of treatment
that will deal with the majority of organisms
responsible for producing each syndrome.
22
Cont`d
Traditional diagnosis of STIs has relied on
identifying the organism causing the
symptoms through sophisticated laboratory
diagnosis.
This is very expensive and impractical in
most developing countries.
23
Cont`d
Even when laboratory facilities are available,
it may take several days to conduct the lab
tests and get the results back.
If the client does not get treatment until the
test results are back, he/she may have
continued to spread the disease during this
period.
24
Cont`d
A consistent and commonly occurring group
of signs and symptoms is known as
SYNDROME.
For example: Urethral discharge might be
caused by C. trachomatis or N. gonorrhoea.
Thus, the symptom of urethral discharge
would be the basis for identifying the
syndrome.
25
Cont`d
The client would then be treated for the most
common infections that might have caused
that particular set of symptoms and signs.
In case of urethral discharge, the treatment
would target both C. trachomatis and N.
gonorrhoea
26
ADVANTAGES
Rapid and effective treatment with no need
for laboratory support
Can begin treatment immediately, thereby
decreasing spread of STIs.
Treatment is available at primary care level.
Multiple drug treatment ensures broad
coverage of pathogens
27
DISADVANTAGES
Requires training of clinicians in syndromic case
management
Lack of specificity in diagnosis means that several
drugs may be used despite the presence of only one
pathogen.
There must be continued epidemiological surveillance
of the organisms that cause the syndromes and their
resistance to drugs.
28
Why Involving sexual partners in
treatment
29
Reasons for treating contacts
To ensure the partner receives treatment for
possible STIs
To prevent the spread of infection by the
untreated partner.
To ensure the client is not infected after
treatment.
30
Beliefs and expectations regarding
telling his or her partner.
Worry about sexual partner being angry and
blaming him/her for unfaithfulness.
Disappointment, anger, suspicion about
sexual partners.
Embarrassment shame and worry.
31
Cont……………………………….
Concern about how to talk to and bring
sexual partners for treatment.
Concerns about whether they will be cured.
Concerns about whether the illness is due to
HIV.
32
6 points the client should consider
telling partners
How the client was exposed and the risk of
infection.
Where to get treatment.
Why sexual activity should be avoided until
disease is cured.
33
Cont……………………………
That the partner may be infected even if she
shows no symptoms.
STIs can cause life threatening complications
The infected person can infect others as long
as he or she is untreated.
36
Gonorrhea
Gonorrhea is commonly known as Chindoko
Incubation period: 1 – 14 days
A bacteria causing gonorrhea is Neisseria
gonorrhoea.
Can cause infections in men, women, and new
babies
The person can easily pass it on to sex partners
and babies during childbirth.

Lymphogranuloma Venerium
[BUBO]
Chancroid and
Lymphogranuloma
venereum (LGV)
cause buboes.
When a bubo is
caused by
chancroid, a genital
ulcer could also be
present, but
occasionally may
not be.
101
If the bubo is caused by LGV, a genital ulcer may not be
present. Buboes may be unilateral or bilateral, thus the groin
must be examined on both sides.
Lymph nodes in the inguinal region may enlarge for a variety
of reasons, which include:-
Septic skin lesions on thighs, leg, foot, toes, buttocks,
anus, perineum, scrotum, penis, labia, vulva and vagina.
Systemic infections such as hepatitis B, HIV infection,
TB, syphilis, infectious mononucleosis.
Other infections such as bubonic plague, cat scratch
fever, trypanosomiasis.

Scrotal Swelling
SS
105
Cont`d
Inflammation of the epididymis (epididymitis) usually
manifests itself by acute onset of unilateral testicular
pain and swelling, often tenderness of the epididymis
and vas deferens, and occasionally with erythema and
oedema of the overlying skin.
In men under 35 years this is more frequently caused
by sexually transmitted organisms than in men over 35
years.
When the epididymitis is accompanied by urethral
discharge, it should be presumed to be sexually
transmitted origin, commonly gonococcal and or
chlamydial in nature.
106
CAUSES
Gonorrhoea
Chlamydia Trachomatis
Bacterium E. Coli
Mumps virus
TB
Klebsiella
Pseudomonas aeruginosa
Coliform in children
107
Cont`d
Scrotal swelling is commonly encountered in
clinical practice.
Symptoms may be due to long standing
problems like hydrocele, varicocele or inguinal
hernia.
Other symptoms may be due to acute illnesses
like torsion of testis, strangulated hernia and
trauma.
108
TORSION OF THE TESTIS
The testis twists around itself causing a twist in
the spermatic cord, blocks the blood supply.
There may be total obstruction of blood supply
to the testis.
This condition is serious and can lead to gas
gangrene and death.
109
CLINICAL FEATURES
Sudden pain and scrotal swelling in one or two
sacs
Abdominal pain
Vomiting
Hot, swollen and tender scrotum
Elevation/rotation of the testis

The person can easily pass it on to sex
partners and babies during childbirth
Herpes
120
Genital Herpes: Two Types
There are 2 types of HSV: HSV-1 and
HSV-2.
–HSV-2 causes most genital infections.
–HSV-1 causes oral infections (cold sores,
fever blisters) and some genital infections.
Herpes
121
Symptoms of Genital Herpes
Numerous painful lesions (sores)
On the penis, vagina, anus, buttocks, thighs,
mouth, or finger
Last up to 4 – 21 days
Other symptoms include headache, fever,
muscle aches, swollen lymph nodes, and
difficult urination.
Symptoms may or may not come back.
Herpes
122
Genital Herpes Without Symptoms
Many people with herpes do not have any
symptoms or do not recognize that they have
symptoms.
Most people with herpes can pass the virus
to sex partners even when they do not have
symptoms.

Genital HPV: Two Types
The types of HPV that infect the genital area
are labeled “low-risk” or “high-risk”
depending on whether they can cause cancer
or not.
Low-risk HPV types can cause genital warts.
High-risk HPV types can cause serious
cervical lesions, cervical cancer, and other
genital cancers.
HPV
135
Symptoms of Genital HPV Infection
Usually asymptomatic and brief (6 – 12 months)
Genital warts (usually infection with low-risk type of
HPV)
Warts on the penis, vagina, anus or urethra
Rarely may have itching, bleeding, burning, or
pain along with the warts
May go away on their own, stay about the same,
or get worse
HPV
136
Symptoms of Genital HPV Infection
Cervical lesions (usually infection with high-risk type of
HPV)
Usually no symptoms
Detected by Pap smear
Most will go away on their own
Some will persist and need to be followed by health
care provider
Most women with high-risk HPV types do not get
cervical cancer
HPV
137
Testing & Treatment for
Genital Warts
Genital Warts
No tests for genital warts
Several types of treatment are available
Warts may come back
Cervical lesions and cervical cancer
VIA smears are best way to detect serious
lesions and prevent cervical cancer.
VIA is recommended for all sexually active
women.
HPV
138
Cancer of the Cervix
Caused by HPV, sexually transmitted
10% of women with HPV will develop precancerous
cervical dysplasia, some will develop invasive cancer of
the cervix.
Post-coital bleeding should be investigated immediately.
Risk factors:
Early sexual activity (before 18)
Multiple sex partners
Exposure to other STIs
Immuno-suppression (due to HIV or steriod use)
Smoking
139
Diagnosis: Pap-smear or VIA
VIA is non-invasive, easy to perform and
inexpensive intervention with immediate results
which can be performed at HC level.
Local supplies: light, speculum, Acetic Acid
(vinegar), swabs and gloves.
VIA is currently available at selected sites
throughout the country
140
Cervical Cancer
Normal cervix with a smooth, glistening mucosal
surface. The cervical os is small and round,
typical for a nulliparous woman.
The os will have a fish-mouth shape after
pregnancy
Invasive Squamous Cell Cancer
Early invasive cancer:
Advanced invasive cervical cancer:
note the bulging, cauliflower-like,
ulceroproliferative growth with
bleeding and necrosis
Dense, chalky white complex acetowhite lesion
with raised and rolled out margin and irregular,
nodular surface suggestive of early invasive
cancer
Adenocarcinoma in situ :
The tips of some of the columnar villi
turn densely white compared to the
surrounding columnar villi after the
application of acetic acid (arrow).
The nabothian cysts turn white after
the application of acetic acid
141
Prevention in General for STIs
Be faithful to one sexual partner
Correct & consistence use of condoms
Treating all sexual partners
